STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not Applicable.

BACKGROUND

The disclosure relates generally to imaging devices used during surgical procedures to visualize a surgical area, and more particularly, but not necessarily entirely, to a system and methods for providing and reclaiming single use imaging devices primarily for sanitized environments.

Endoscopic surgery is experiencing rapid growth in the medical field. Endoscopy is a minimally invasive surgical procedure that is used to analyze the interior of a body cavity or interior surfaces of an organ by inserting a tubular member into the body cavity through a minor or minimal incision. A conventional endoscope is generally an instrument with a light source and an image sensor or device for visualizing the interior of a body cavity. A wide range of applications have been developed for the general field of endoscopes including, but not necessarily limited to: arthroscope, angioscope, bronchoscope, choledochoscope, colonoscope, cytoscope, duodenoscope, enteroscope, esophagogastro-duodenoscope (gastroscope), laparoscope, laryngoscope, nasopharyngo-neproscope, sigmoidoscope, thoracoscope, and utererscope (hereinafter referred to generally as “endoscope”). The advantages of endoscopy include smaller surgical incisions and less soft tissue damage. As a result, there is significantly less discomfort and pain for the patient as well as a decrease in recovery time.

The advantages of minimally invasive surgery performed with the help of an endoscope are well known and understood in the medical field. As a result, there have been a growing number of devices for use with endoscopes for delivering, for example, diagnostic, monitoring, treatment, operating instruments, tools, and accessories (collectively, “tools”) into the observation field and working space of the physician's endoscope.

As part of forming an image of the surgical site, the endoscope includes a light source and an image sensor. Endoscopes may also incorporate more than one tubular member for observation or operation within the body, such as a working channel for passing diagnostic, monitoring, treatment, or surgical tools through the endoscope. Endoscopes include glass lenses and an adjustable ocular or eye piece, a lateral connection for a light conductor, an adaptor that allows focusing, and a camera head. This configuration is also called a video endoscope.

Additionally, imaging devices are subject to governmental regulations, for example the FDA in the United States, to protect patients and surgeons from potential infections. These devices may be made and processed in accordance and consistent with international and national regulations for medical environments. The disclosure is directed to a system and method for serializing a medical device, specifically an imaging device such as a camera head.

It is axiomatic that strict sterilization of the operating room and surgical equipment is required during any surgery. The strict hygiene and sterilization conditions required in a “surgical theater,” i.e., operating or treatment room, necessitate the highest possible sterility of all medical devices and equipment. Part of that sterilization process is the need to sterilize anything that comes in contact with the patient or penetrates the sterile field, including the endoscope and its attachments and components. It will be appreciated that the sterile field may be considered a specified area, such as within a tray or on a sterile towel, that is considered free of microorganisms; or the sterile field may be considered an area immediately around a patient that has been prepared for a surgical procedure. The sterile field may include the scrubbed team members, who are properly attired, and all furniture and fixtures in the area.

In recent years there has been a trend of providing a single use endoscope and components as a packaged, sterilized product, similar to a package containing a surgical implant, such as a knee or hip implant. In terms of endoscopy, instead of using endoscopes that have been reconditioned for each new surgery through traditional sterilization procedures, it means using a single use endoscope and components that are delivered to the hospital in a sterilized package. Due to this trend, it has become increasingly difficult to ensure that each endoscope and its components are properly cared for, used and sterilized for single use and not simply re-sterilized using traditional sterilization procedures.

Traditional drawbacks or problems of video endoscopes include a lack of image quality, the need for sterilization and high manufacturing cost as well as high processing cost. To address these and potentially other problems, the disclosure utilizes unique imaging devices or sensors in addition to a unique method, system and process for providing and reclaiming single use imaging devices.

The features and advantages of the disclosure will be set forth in the description that follows, and in part will be apparent from the description, or may be learned by the practice of the disclosure without undue experimentation. The features and advantages of the disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out herein.

SUMMARY OF THE DISCLOSURE

An embodiment may comprise a single use camera used for general purpose surgical procedures including, but not limited to: arthroscopic, laparoscopic, gynecologic, and urologic. An embodiment may comprise an imaging device that is a sterile and designed to ensure single use. An embodiment may be an imaging device that comprises a single imaging sensor, either CCD (charge coupled device) or CMOS (complementary metal oxide semiconductor), encased in a molded plastic housing. It will be appreciated that the housing may be made from metal, carbon fiber or other suitable materials usable as an imaging device housing. The imaging device may further comprise the means to be attached to an optical coupling device, using C-Mount and CS-Mount threads or another proprietary or unique connection method. It is within the disclosure to include integrated optical systems, such that no specific coupling means is required. The imaging device may further comprise a cable or wireless method to transmit data to and from a camera control unit. An embodiment may further comprise a thermal energy dissipation means such as a heat sink or cooling mechanism. An embodiment may further comprise an electrically isolated imaging device, for example a camera head.

In an embodiment, information will be recorded in the memory of the imaging device each time it is used in a procedure or quality control (QC) checked at the manufacturer. This information may be used to evaluate usage time, expiration date, etc. An embodiment may comprise features to ensure that the imaging device is only used once and that the imaging device is safe for use.

In an embodiment, the imaging device may be fully covered in plastic having a sensor heat sink to ensure the camera head meets cardiac floating (CF) and body floating (BF) ISO standards. It will be appreciated that the imaging device may be fully covered in metal, carbon fiber or other suitable materials usable as an imaging device housing. An embodiment may comprise an imaging device that may be stamped with the current time when plugged into a console in the field after a quality control check has been performed. This time may be used as a baseline for usage. If the imaging device is powered off for a predetermined period of time, which may be equivalent to a sterilization cycle, then the imaging device will not function. The imaging device may display an onscreen message telling the user that the camera has already been used and will not allow current operation. These features ensure the imaging device will not be used more than one time per sterilization cycle and further ensures that proper sterilization is performed by the manufacturer or other authorized source. This function is to protect the patient and the doctor from an invalid or unsafe use as well as liability of the manufacturer.

In an embodiment an active imaging device may be attached to a control unit. The control unit will check the last sterilization date and ensure that the imaging device is no older than a predetermined safety date. If the imaging device is older than the required date, an onscreen warning will tell the user that the imaging device has expired and is unsafe for use. These features will protect the patient and the doctor from using a non-sterile imaging device.

In an embodiment a security code or some other means of identifying, and validating for use, an imaging device by a control unit may be provided in order to verify that the imaging device is authorized for use. A validating security code or procedure of validation may be distributed to control units from a central database over the internet, by direct transfer from portable storage device such as USB device containing memory, another computer, or other storage device.

An embodiment may comprise methods for processing single use camera heads including quality control checking, functionality checking, sanitization or sterilization, packaging, transporting, use and reclamation, and reading and writing to memory within the imaging device. An embodiment may comprise a network of components, and may further comprise the ability to update the imaging devices.

With reference primarily to FIG. 1, an embodiment of the features of the disclosure will be discussed generally. FIG. 1 illustrates a system 100 for providing a digital image using a remote imaging device 110 that may be tethered electronically and physically to a control unit 120. The control unit 120 may be configured to exchange data with imaging device 110 in order to provide single use functionality and safety in a sterile environment, such as an operating room, a doctor's office or dental office. Additionally, the control unit 120 may be electrically connected to a computer 130 or external monitor 140 for increased functionality.

Referring now to FIG. 2 where the imaging system 100 will be discussed in greater detail. As is illustrated in FIG. 2, the imaging device 110 can be connected or disconnected from the control unit 120 by way of an electronic connector 114 on the imaging device 110 that is configured to electronically and physically interact with a corresponding electronic connector 126 on the control unit 120. The ability to disconnect the imaging device 110 from the control unit 120 provides the ability to easily replace a used imaging device 110 for a sterilized, renewed imaging device 110. The imaging device 110 may have a head portion 112 generally positioned remotely from the electronic connector 114, thereby allowing greater mobility of the head portion 112 during use.

Also illustrated in FIG. 2 is an embodiment of the control unit 120 having an electronic connector 126 therein for receiving the corresponding electronic connector 114 of the imaging device 110. The control unit 120 may also have a display 128 for conveying information during a procedure to an operator or user. The display 128 may also comprise interactive functionality allowing an operator to enter commands or change what information is being displayed. Such functionality may be provided by a touch screen system as is commonly known. The control unit may also have video inputs 122 and video outputs 124 for transferring image data to other apparatuses for increased functionality. As illustrated in FIG. 1, common apparatuses may be a computer 130 or an external monitor 140.

Referring now to FIG. 3 an imaging system 300 will be discussed having wireless capability and features. As is illustrated in FIG. 3, the imaging device 310 may communicate with a control unit 320 by way of wireless transmissions such as Wifi, infrared, bluetooth etc. Other forms of wireless non-tethered connectivity may also be used for providing communication between the imaging device 310 and control unit 320, including but not limited to, radio frequency from any available spectrum, infrared of all configurations, ultrasonic, and optical. The imaging device 310 may comprise a head portion 312 that houses an imaging sensor, memory and associated circuitry, which will be discussed in greater detail below. It will be appreciated that in a surgical application, the quality of an image and the ability to adequately view the surgical site is a priority for a surgeon.

The imaging sensor used in the camera head may be a single sensor. Due to the ability to make smaller sized sensors, the single sensor may be located or positioned anywhere along the endoscope. For example, the sensor may be located or positioned proximally with respect to the endoscope, or at the distal end of the endoscope without departing from the spirit or scope of the disclosure. In an embodiment, the imaging sensor may be located on a tip of a device, i.e., in a chip-on-the-tip configuration, such as on the distal end of an endoscope or other component.

It will be appreciated that the imaging sensor may be a combination or plurality of sensors that work together to create a three-dimensional image. The single imaging sensor or the combination or plurality of imaging sensors may be high definition sensors for purposes of creating a high quality image, such that images may be viewed in a high resolution, for example 1920×1080 pixels or any other high definition standard, such as 1280×720 pixels.

The image sensor may be located on a rigid endoscopic member or a flexible endoscopic member. For example, the image sensor may be located on a distal end of an articulating member, such that the sensor may articulate or move for better positioning within a surgical site. In such a case, the camera may be a flexible camera head. It will be appreciated that as the imaging sensor is located closer to the distal end of the endoscope, visualization may be improved. Improved visualization may be due to the amount of light available for the sensor to create an image when the sensor is located distally with respect to the endoscope. Because the location of the sensor may be closer to where the light is being concentrated or focused there may be improved visualization. Thus, in various embodiments, the imaging sensor may be located on a distal end of the endoscope. Further, the imaging sensor may used in a multi-port or single port surgical application. In a single port application, there may be multiple channels through which flexible and rigid instrument delivery tubes are inserted.

The head portion 312 may further comprise a wireless transceiver 314 for communicating with a corresponding wireless transceiver 322 housed in the control unit 320. The ability to separate the head portion 312 from the control unit 320 via wireless transmissions may provide for the easy replacement of used imaging devices for sterilized and renewed imaging devices. In other words, the wireless communication may be enabled by an electronic communication circuit that is a wireless communication transceiver configured to communicate wirelessly with a corresponding transceiver on said control unit using any of the above noted wireless technologies. The wireless functionality also allows for greater mobility of the head portion 312 during use. It will be appreciated that the wireless features and functionality may be incorporated into any of the embodiments disclosed herein or embodiments that fall within the scope of this disclosure.

Also illustrated in FIG. 3 is an embodiment of the control unit 320 having wireless capabilities and features. A transceiver 322 may be provided in or as part of the control unit 320 for receiving and transmitting wireless data to the imaging device 310. The control unit 320 may also have a display 328 for conveying information during a procedure to an operator or user. The display 328 may also comprise interactive functionality allowing an operator to enter commands or change what information is being displayed. Such functionality may be provided by a touch screen system as is commonly known. The control unit 320 may also have video inputs 321 and video outputs 324 for transferring image data to other apparatuses for increased functionality. As illustrated in FIG. 1 common apparatuses may be a computer 130 or an external monitor 140. It is within the scope of this disclosure to include an imaging system comprising both wired and wireless communication capabilities.

Illustrated in FIG. 4 is an embodiment of the control unit 420 disconnected from an imaging device that is illustrated as being connected to complementary apparatuses. A connector 426 may be provided therein for transferring data to and from an imaging device. The ability to separate the imaging device may provide for the easy replacement of used imaging devices with sterilized and renewed imaging devices. The control unit 420 may also have a display 428 for conveying to an operator information during a procedure. The display 428 may also comprise interactive functionality allowing an operator to enter commands or change what information is being displayed. Such functionality may be provided by a touch screen system as is commonly known. The control unit may also have video inputs 421 and video outputs 424 for transferring image data to other apparatuses for increased functionality. Common apparatuses may be a computer 430 or an external monitor 440 there by increasing the technical functionality of the system 400. A computer 430 may be used for storing the digital output from the imaging system or may be used to enhance and provide further adjustment within the system. An external monitor 440 may be used to show real time digital images to aid an operator in the use of the system, or later review and study the recorded digital imagery.

Referring now to FIG. 5 an embodiment of a control unit display 428 that may be part of a control unit 420 will be discussed in greater detail. The display 428 may be a digital display of liquid crystal design (LCD), or the display may be some other technology beside LCD, and may have touch screen functionality and capability for an operator or user to input commands into the system 400. The embodiment discussed herein may have input portions 428a and 428b whereby an operator or user may input commands into the system 400. The embodiment may further comprise a status portion 428c informing a user about the operational status of the components of the system 400. For example, display portion 428c may display an error message related to the condition of an attached imaging device 410 if the imaging device 410 has already been used or has been deemed unfit for a procedure. The display 428 may also have a dedicated message portion 428d providing instructions and further information to an operator or user. The configuration of the display 428 may change during use to accommodate further functionality. A plurality of displays 428 is contemplated by, and falls within the scope of, this disclosure and may be used alternatively or in conjunction with this embodiment. An embodiment may comprise a key pad or a button pad for control purposes within a control unit.

Illustrated in FIGS. 6 and 6A is an embodiment of a retractable display 428 of a control unit 420. The display 428 may have a first or retracted position within the control unit 420 (illustrated best in FIG. 6) that may be used to protect the display 428 when it is not being used. The display 428′ of FIG. 6A illustrates how the display may be deployed into a more user readable position, as it has been extended and rotated outward.

A window 755 may also be incorporated into the embodiment for facilitating the transmission of light from an optical accessory to an image sensor 775. The image sensor 775 may be mounted to a supporting printed circuit board or supportive substrate 770. An electronic connector 778 may be incorporated to electronically connect the image sensor 775 to a main circuit or main printed circuit board 760. A main wiring harness 782 may be incorporated into a wired tether 780 thereby electrically connecting the components of the imaging device head 712 to a control unit.

The imaging device head 712 may further comprise a memory 788 or memory circuit allowing the storage of data within the imaging device head 712. It will be appreciated that memory may be any data storage device that is capable of recording (storing) information (data). Data that may be stored or written into memory 788 may include an identifying serial number that uniquely identifies an imaging device. Other data that may be stored or written into memory 788 may include data such as the amount of the time the imaging device has been used, i.e., the hours of operation, or the amount of time the imaging device has been powered on. Data that may be written into memory 788 may include sterilization data or renewal data, representing the working condition of the imaging device.

With reference to FIG. 14, a method of using an imaging system consistent with the embodiments disclosed herein will be discussed. In use, a sterilized single use imaging device 1201 will be provided that may comprise memory 1202 at 1410. At 1420 a user may connect the single use imaging device 1201 to a complementary control unit 1220 both electronically and physically. At 1430 the control unit 1220 may initiate a process of reading memory 1202 and registers the serial number of the imaging device 1201. At 1440 the system causes a value to be recorded into memory 1202 indicating that the imaging device 1201 has been used. At 1450 the system records into memory 1202 the date and time the imaging device 1201 is connected to the control unit 1220. At 1460 a timing process is initiated by the control unit from the base line time recorded at 1450 and tracks or times the duration that the imaging device 1201 is used and the duration is recorded into memory 1202 at 1470. After use, the imaging device 1201 is disconnected from the control unit 1220 at 1480 and then discarded for renewal or reclamation.

At 1510 the imaging device 1201 may be connected to a testing control unit or a master control unit. At 1515 the components of the imaging system may be authenticated according to the teachings and principles of the disclosure (see discussion in relation to FIG. 30 below). At 1520 the testing control unit or master control unit causes the data stored in memory 1202 to be recorded into storage on the testing control unit or master control unit as stored, in order for the specific imaging device 1201 to be renewed. At 1525 a value is placed in memory 1202 indicating that the imaging device has been renewed and is ready for use such that when connected to another control unit for use it will operate. The location and date of the renewal may then be recorded into memory 1202 at 1530. At 1540 the imaging device 1201 can be sterilized and (at 1550) placed in a protective sterilized package.

With reference to FIG. 16 an alternative embodiment of a method of use will be discussed illustrating safety settings of the embodiment. At 1610 the memory imaging device head may be stamped with time of manufacture when it is plugged into the master control unit or master console after assembly in the field, i.e., in an operating room, and after a quality control check has been performed. At 1620 a check may be made to determine if the imaging device has been powered off for a predetermined number of minutes, such as a time frame that is close to what a typical sterilization cycle would last. At 1630, if the imaging device has been powered off the predetermined amount of time the control unit will display an onscreen message telling the user the imaging device has already been used, and will not allow further operation, such that no image will be produced through video feed. This feature will ensure the imaging device, i.e., the camera, will not be used more than one time per sterilization cycle. This feature also protects the patient and the doctor from an invalid or unsafe use and foreseeable misuse.

Referring to FIG. 17 an embodiment of a method of use will be discussed. During use, an imaging device may be connected to a control unit. Upon connection, an electronic communication connection is formed between the imaging device and the control unit. At 1702 the imaging device may be powered on by power supplied by the control unit. At 1704 a processor in the control unit may cause data regarding imaging device identification that may be stored in a memory within the imaging device to be read. At 1706 a processor in the control unit may cause data regarding the manufacturing date of the imaging device to be read from memory within the imaging device. The processor in the control unit may then compare the data to a predetermined data value range. At 1707 an error message may be displayed if the read data is outside the predetermined data value range and the imaging device will be stopped from operating. At 1708 a processor in the control unit may cause data regarding the reclamation of the imaging device to be read from memory within the imaging device. The data regarding reclamation of the imaging device may include data representing whether or not the imaging device has been previously used. The processor may then compare the data to a predetermined data value range. At 1709 an error massage may be displayed if the read data is outside the predetermined data value range and the imaging device will be stopped from operating. At 1710 a processor in the control unit may cause data regarding the reclamation date of the imaging device to be read from memory within the imaging device. The processor may then compare the data to a predetermined data value range. At 1711 an error massage may be displayed if the read data is outside the predetermined data value range and the imaging device will be stopped from operating. At 1712 a processor in the control unit may cause usage information of the current procedure to be monitored to note whether imaging device has been unpowered for a predetermined period of time and then re-powered. If this condition occurs it is possible that the imaging device has been tampered with or that an attempt has been made to sterilize the imaging device and use it a second time. The predetermined period of time may correspond to the amount of time a typical sterilization process would normally take. The processor then compares the data to a predetermined data value range. At 17013 an error massage may be displayed if the data read is outside the predetermined data value range and the imaging device will be stopped from operating. At 1714 a processor in the control unit may cause a value to be placed in memory in the imaging device indicating that the imaging device has been used. At 1716 a processor in the control unit may cause the date and time of use to be recorded in memory in the imaging device. Additional information may be recorded into the memory of the imaging device such as, for example, duration of use, procedure settings, and user settings and any other data suitable for recording to memory. The imaging device may be disconnected from the control unit and thereby powered off at 1718.

Referring now to FIG. 18 a method of reclaiming an image device after use will be discussed. It should be noted that a single use imaging device may comprise the durability to be used a plurality of times, however sterilization requirements may prevent an imaging device from being used more than once without a process for reclaiming the imaging device, thereby returning it to a sterilized condition. A method of reclamation for an imaging device may comprise the process of powering on the imaging device at 1802, when the imaging device is electrically connected to a control unit. At 1804 a processor in the control unit may cause data representing identification information for the imaging device to be stored in storage in the control unit. A control unit may be a master control unit configured for reclaiming the imaging devices. The master control unit may track a plurality of imaging devices thereby keeping a catalog of associated information such as use and condition of the device or devices. At 1806 a processor in the control unit may cause that data representing a manufacturing date to be read and compared to a predetermined value or range of values. If the read data is out of the predetermined range value, an error report may be issued at 1807. At 1808 a processor in the control unit may cause data representing use data written in memory of the imaging device to be read and recorded into storage in the control unit. At 1810 a processor may cause data representing a date and time of reclamation to be recorded into memory in the imaging device. At 1812 a processor in the control unit may cause that data representing the number of uses of the imaging device to be read and recorded into storage in the control unit. The processor may compare the read data to a predetermined value or range of values to determine whether the imaging device is fit for continued use. If the predetermined value is exceeded an error message may be displayed (at 1813) and the imaging device may be retired. At 1814 a processor in the control unit may initiate a test or quality control check of all the circuitry in the imaging device to ensure that the device is functional. At 1815 it may be determined that the imaging device failed the quality control check and an error massage may be displayed. At 1816 the imaging device can be reset for use. The resetting process may comprise writing data to the memory of the imaging device indicating that the imaging device has been reclaimed and sterilized. At 1816 the device may be disconnected from the control unit and physically sterilized and repackaged.

With reference primarily to FIG. 19, an embodiment of a method for making an imaging device having memory therein for use in a sterilized environment will be discussed. At 1902 an imaging device may be powered on upon being connected to a control unit. The control unit may be a master control unit configured for the manufacturing process. At 1904 a processor in the control unit may cause that data representing an identification serial number for the imaging device to be written into memory of the imaging device. At 1906 a processor in the control unit may cause that data representing the location of manufacture be recorded to memory in the imaging device. At 1908 a processor may cause that data representing the date of manufacture may be recorded into memory on the imaging device. At 1910 a processor in the control unit may initiate a test or quality control check of all the circuitry in the imaging device to ensure that the device is functional. At 1912 the imaging device may be unplugged from the control and sterilized for packaging.
